Outcomes of 60-Degree Nasal Goniotomy for Open Angle Glaucoma
Espaillat AJournal of Glaucoma 2023; 32: e129-e134
PRCIS: Sixty-degree nasal sectoral juxtacanalicular space goniotomy with the single-use Espaillat juxtacanalicular space slider device significantly reduced intraocular pressure and the number of required glaucoma hypotensive medications, with sustained reductions over 24 months. PURPOSE: This study analyzed the safety and efficacy of the Espaillat juxtacanalicular space slider during minimally invasive 60-degree nasal sectoral goniotomy for mild-to-moderate open angle glaucoma (OAG). PATIENTS AND METHODS: This prospective, observational case series performed at a private clinical practice and outpatient surgery center assessed the eyes of patients with mild-to-moderate OAG who underwent phacoemulsification cataract surgery with 60-degree nasal sectoral goniotomy using the Espaillat juxtacanalicular space slider. The same surgeon performed all procedures. Intraocular pressure, intraocular pressure-lowering drugs, and adverse effects were assessed over 24 months, and a regression analysis of intraocular pressure reduction was performed. Success was defined as (1) A reduction in the intraocular pressure of at least 20% for at least 12 months, compared with the baseline value, and (2) a decrease in the number of medications by at least one for at least 12 months. RESULTS: Among 38 eyes, 27 (72%) had moderate glaucoma, and 11 (28%) had mild glaucoma. Postoperatively, intraocular pressure was decreased by 38% at 12 months (mean 13.7±1.7 mmHg), 35% at 18 months (mean 14.4±1.8 mmHg), and 31% at 24 months (mean 15.2±1.9 mmHg). In addition, the number of topical glaucoma medications used decreased from a mean of 1.6 to 0.4 ( P <0.001). The main adverse event was temporary focal corneal edema (29 patients; 76%). CONCLUSIONS: Using the Espaillat juxtacanalicular space slider during invasive 60-degree nasal sectoral goniotomy for OAG yielded a significant and sustained reduction in intraocular pressure and reduced the need for glaucoma medications with minimal adverse events.
